I assume from this statement that you are paying or have paid for your education. If someone said to you "let me violently smash your leg so bad that it needs a metal plate and 8 screws, and I'll cover your education bills", would you say yes? A lot of football players do not only show up for the love of the game, for some it's the only way to get an education. So even if they'd rather not have their leg smashed or their brains scrambled, this is what they have to lay on the line. And for the the 20% or so of the team that get zero assistance, they are playing for the love of the game. Sure being on the football team gets you laid more than not being on the team, but other than that, not a lot of benefit if you're doing it for free. Do they deserve to have permanent injuries, or is it only the scholar-shipped players? Or is it fair that giant organizations can benefit from these non-scholar-shipped athletes, or should they only benefit from the scholar-shipped athletes?
I realize I am being a bit dramatic, but when people feel that all these players get their "free" education or have things so easy, that they have no reason to bitch, they don't see the entire picture. Scholar-shipped or not, these players put in tons of hours with football related activities, and no, don't bother saying NCAA mandates only 20 hours. I've known loads of players at Wyoming and 20 hours would have been an off week. They are also held to a certain standard for this free education. 2.0 average or you can't play, if you can't play, they don't keep you around. They aren't allowed to work, so if their family economic situation is not so good, they miss out on many of the things other students have.
So yes, if all goes well, no injuries, etc, they can walk away with a degree and an in tact body. But any number of variations and it doesn't work out so well (bad injury, can't keep the grades up because you're spending too much time being a better player, get a comp tattoo or drink in a bar because you can't afford one and you're gone, etc.).
It's a trade off, but one that I believe is not in favor of the average football player.
